If you're counting pre-workout and post-workout shakes, UFC fighter Brian "All-Amercian" Stann eats a whopping 11 meals a day in peak training season. Are all these meals really necessary? On days you do three separate workouts, they most certainly are.

"If you're going to be a serious athlete, you need to be dedicated and disciplined not just in the gym but also with what you put in your body," says Stann, a rising middleweight and decorated combat veteran.

"That's the fuel that's going to allow you to perform. You're going to get out of your body what you put into it." Stann's diet - thanks in part to his wife, Teressa, who has a degree in nutrition and dietetics - is especially clean, consisting of quality protein sources like chicken breast, salmon, and egg whites; a variety of fruits and vegetables; and healthy fats from almonds.
